Mail admins wanting matching forward/reverse DNS and hostnames that don't "look dynamically generated" is probably more of a human than an RFC thing: "We used to get a lot of spam from dialup IPs, or IPs without matching reverse DNS, so let's reject anything that comes from an IP without FcRDNS and greylist anything with more than X dashes and Y dots in it's hostname."
